For Loops Not Executing Correctly in SimpleScript

Description

In SimpleScript, for loops do not execute as expected. When using a typical loop like for (let i = 1; i <= 5; i++), the loop either does not iterate correctly or breaks prematurely. This disrupts core control flow functionality and limits usage in real-world scenarios.

Steps to Reproduce

1. Write a SimpleScript program with a for loop:

   for (let i = 1; i <= 5; i++) {
       print(i);
   }
   

2. Run the script using the interpreter/web interface.
3. Observe the output.

Expected Behavior

The loop should print the numbers from 1 through 5:

1
2
3
4
5

Actual Behavior

The output either shows only the first value, skips iterations, or nothing is printed at all.

Possible Causes

• Off-by-one error in loop bounds
• Interpreter not handling loop initialization or increment properly
• Incorrect tokenization or parsing of the for loop structure

Environment

• SimpleScript Version: Latest from main
• Platform: Web (https://simple-script-five.vercel.app/)
• Browser: Chrome/Firefox

Additional Context

This issue affects the usability of SimpleScript in basic looping tasks and may hinder educational use cases. A fix should ensure:

• Proper parsing and evaluation of loop bounds
• Execution of loop body on each iteration
• Correct variable scope management

Please investigate and fix the issue. Happy to test and provide feedback!
